Reaction Steps

A solution of 1-(4-piperidinyl)-1,3-dihydro-2H-benzimidazol-2-one (1.10 g, 5.05 mmol), 2,2,2-trifluoro-N-{2-[(2-methyl-2-oxiranyl)methoxy]phenyl}acetamide (1.39 g, 5.05 mmol) in EtOH (95%, 20 ml,) was stirred for 2 h at 78° C. Ammonium hydroxide (25%, 7.5 ml) was added to the reaction mixture and heating was continued for additional 5 h. After standing over night at room temperature the reaction mixture was concentrated and the residue was purified on silica (dichloromethane-methanol, 12:1, containing 1% of NH4OH (25%)) to give the subtitle compound (1.54 g).
